Poor sleep has 2.4 times higher risk of death due to heart diseases or others, and 2 times higher increase ratio of cancer cells, compared to good sleep.
According to a research performed in Oxford University in England, 14 poor sleepers chosen randomly wrote about stressful events and emotional experience at that time for 3 nights. Before the experiment, the average of their sleeping onset latency was 40 minutes, but after the experiment, it became 14 minutes.
Writing about stressful events and the emotional experience at that time leads to looking at the stressful events objectively. That reduces stress, stabilizes the condition of autonomic nervous system and leads to the improvement of sleep.
This method is used as a treatment method for insomnia in England and some other countries.
A 64 year-old woman who had been suffering from insomnia tried the experiment for 5 days. She has difficulty to fall asleep and wakes up 3 times at the middle of night.
The method is writing about stressful events and the emotional experience at that time before going to bed for about 15minutes.
It is important to take about 15 minutes to process the stressful events. The paper can be torn up and thrown after writing.
She didn’t think of any stressful events in her daily life before the experiment, but she recognized that she had complaints about her husband by writing.
After 5th night, she only woke up once for urination, but after that, she didn’t wake up until the alarm set off. She reported she could sleep well the first time in 2 years.
